5.4 PBX Integration Malfunctions
SYMPTOMS
CORRECTIVE ACTIONS
Simple In-Band DTMF integration not
working.
§
Monitor the WIN port with a test set. Verify
that the PBX is sending DTMF digits when the
call is made to the WIN or a call is forwarded to
the WIN. If no digits are being sent, check the
PBX programming for Voice Mail integration.
If digits are being sent continue with the
following checks.
§
WIN ports are not configured for In-Band
integration. Check “Line Configuration” in the
On-Line Configuration Editor. The “Digital
Parameter” must be selected for each line that
needs to be integrated.
§
WIN is not recognizing the DTMF digits being
sent. Check the Touch Tone Verification delay
during playback in “System Hardware
Configuration” in the Off-Line Configuration
Menu. This value should be 4 for Dialogic
VLC’s.
§
Check the “In-band Packet Timeout” in the
“Digital In-Band Integration Control” menu in
the On-Line Configuration Editor. This value
should be at least 2. It may be necessary to
increase this value to 3 if the PBX is sending the
digits too slowly and is not finished sending
before the timeout period.
§
Check the Offhook delay parameter in “System
Hardware Configuration” in the Off-Line
Configuration Editor. This parameter controls
how soon the system can receive digits after
going off hook. This parameter should be set to
5 (50 msec.) For all in-band integrations.
Digital In-Band or packetized in-band
integration not working.
§
For digital in-band integration, verify that the
ports are connected to the proper digital ports on
the PBX. Turn on the line trace and call the
WIN port. You should see “Received in-band
sequence...”.
§
Verify that the PBX extensions connected to the
WIN ports are setup properly in the PBX
